Jimmer, I've been looking at your Swedish movement problem, and don't get exactly the same results you do, though there are a couple of glitches.
First of all, the file you attached doesn't exactly match the jpg, inasmuch as in the file there's no depot under the Swedish corps, and all your depots are in use. However, if I destroy a depot elsewhere and build it in Sveaborg, the corps is in supply--up to a point.
When you first click on the corps, its potential movement ends at the Russian depot to the east, but it can actually move farther; you just have to decide whether to eat the depot or not. If you say yes, you have to stop there (as per the rules). If you say no, you can continue.
However, clicking movement is a little awkward on the map there--at least with my display. If you're in the space between Sveaborg and Viborg, and click on Viborg, it looks as if you haven't moved (though actually the counter shifts microscopically to the right). Nevertheless, it registers as being in the Viborg area. You can continue as far as St Petersburg, which is as far as you should be able to go.
Now, the supply is a problem, but I'm not sure whether this is a bug or not; I think it is, but it may be a gray area. If you remain in Sveaborg on your depot, you're in supply. If you go one space east, you're in supply. But if you cross the frontier to Viborg or beyond, you're out of supply, even though you're not out of range of the depot.
I suspect this is because France and Russia are not at war, and so--although you can use French depots to supply the Swedish corps--the game doesn't want you to trace "French" supply through Russian territory. I think you probably should be able to, since Sweden is at war with Russia, and it's a Swedish corps and the supply originates in Swedish territory; but I guess it's debatable.
Yes, I built the depot during the turn. But, the saved game files are from the beginning of the phase.
Actually, I didn't want to go to Viborg. I just wanted to go one space east, and it wouldn't let me. Quite possibly for the "messed up" stuff you point out.
Try attacking the corps one space north of Sveaborg. In that space, I'm supposedly out of supply.
At LAST! The greatest campaign board game of all time is finally available for the PC. Can my old heart stand the strain?
